I must agree that this game is damn awesome.
Killmenow, the trick on snipers is force seeing, have that at full power and you can dodge incoming projectiles, crazy but true. (it lets you see them come before they hit I believe)
Force speed is sweet, slowing down the world like Max Payne's bullet time while you're going at high speed.
Force push and pull though are fun, just knocking rows of stormtroopers down. Grip is also fun since you can fling someone across the room: Reactor core anyone?
A favorite trick on the Dark Reborn is to choke them, then throw the lightsaber at them while throwing them across the room, deadly combo.
Multiplay on my 56k modem is fine in a lightsaber duel with up to 4 people, in a gunfight 3 people. Higher then that it goes from silky smooth to standard modem jitters.
